如何检测Apple TV Siri Remote按钮的按下情况? [英] How to detect Apple TV Siri Remote button presses?

问题描述

根据Apple TV界面指南 ，当涉及到游戏时，如果您不在游戏的主菜单中，则应将菜单按钮用作暂停按钮(在这种情况下，应返回Apple TV OS菜单).但是，我在任何地方都找不到应该如何检测来自遥控器的硬按钮输入(与屏幕上的软按钮相对).

According to the Apple TV interface guideline, when it comes to games you're supposed to use the menu button as a pause button when you're not at the main menu of the game (in which case it should return to the Apple TV OS menu). However, I can't find anywhere how you're supposed to detect the hard button input from your remote (as opposed to soft buttons on screen).

我确实找到了

I did find this short programming guide to using controllers that almost seems to imply that you're supposed to use the remote as a controller in this case, but I can't help but think there's a simpler way. ex.

 -(void)buttonPressBegan:(NSEvent*)event

等等(那不是真的.我只是希望有类似的东西).有什么/可以通过检测的方式检测到这一点?

etc (that's not real... I'm just hoping there's something like that). What is/Is there a sanctioned way of detecting this?

推荐答案

Apple建议使用UITapGestureRecognizer来检测按钮何时被释放.

Apple suggests using a UITapGestureRecognizer to detect when a button is released.

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController {
    UITapGestureRecognizer *tapRecognizer;
}

-(void)viewDidLoad {
    [super viewDidLoad];

    tapRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleTap:)];
    tapRecognizer.allowedPressTypes = @[[NSNumber numberWithInteger:UIPressTypeMenu]];
    [self.view addGestureRecognizer:tapRecognizer];
}

-(void)handleTap:(UITapGestureRecognizer *)sender {
    if (sender.state == UIGestureRecognizerStateEnded) {
        NSLog(@"Menu button released");
    }
}
